I have been using mosh on and off, and actually appreciated that the software was so robust that it just works without frequent updates, and as far as I understand, most security is in ssh, so there would not really be a need for a new version.
- loeg 4y agoYour understanding is sort of mistaken. Mosh does an initial handshake over ssh, but after that it’s a custom UDP protocol. There have been and could be more security bugs in that UDP protocol.
- jbj 4y agoAhh, thanks for clarifying! Yes, in that case it is very appreciated to see recent updates.
- achernya 4y agoThe only mosh CVE [1] was in the terminal emulator (a DoS that could only be triggered by a local user), not in the protocol. There have been no vulnerabilities in mosh's UDP protocol. [1] https://nvd.nist.gov/vuln/detail/CVE-2012-2385 https://nvd.nist.gov/vuln/detail/CVE-2012-2385
- nibbleshifter 4y agoyet. I wonder if anyone's thrown a fuzzer at it.
- achernya 4y agoYes, mosh has fuzz tests in oss-fuzz [1]. [1] https://github.com/google/oss-fuzz/tree/master/projects/mosh https://github.com/google/oss-fuzz/tree/master/projects/mosh
